There is word circling the hunter community of a human who consorts with demons on a regular basic.

It is said that the man willing sleeps with them. That he lived with a vampire that was famed for kill everyone in an orphanage. That he works with a sorcerer and witch that raises demons and the dead for their own enjoyment and use. And that the man work with young girls who are possessed by demons and he does nothing to help from the girls from their horrible fate

And finally it is said that in exchange for the ability to see the future he allowed his eye to be removed so he could help the demon possessed girls to fulfill their dark goals.

The hunting community decide the best thing to do with such a evil person is to kill him, so now it's all hands out to end this bastard's life before he ends the world.

Main Crossovers = Buffy, Charmed, Supernatural

What If Xander had a brother who died before Jesse & Xander reacted by extensive training so he could protect himself, his platonic soul mate Jesse & his emotionally stunted step sister Willow – however after Jesse death he moves from defence to offense and starts nightly hunts & mapping out the various lairs, nests, caches, deaths...etc so he can regularly hit the hot spots

Leads to major conflict with the overbearing & willfully blind special syndrome gang = Willow{conflicts with her fantasy version of Xander}, Buffy{wants to subject her version of normal on him} and Giles{impractical snobby researcher & council lackey}

Training = Supernatural, Self Defence, Demonic, Tracking, Weapons, Paranormal, Strategy, First Aid, Thieving, Magical...

Bonus Points if Xander is a part of an old & unique natural born witch family that has hunted ALL styles of demonic/supernatural/paranormal/magical threats, something which is reflected in their comprehensive book of shadows = leads to him having Leo as his Whitelighter/Mentor, a supportive power{empathy or Sensing evil} & a highly destructive active power{energy blasts-pyrokinesis-molecular combustion-energy waves-advance telekinesis-energy balls-molecular dispersion...}

Bonus Bonus Points if Xander is shown as highly practical, knowledgeable, competent, proactive, realistic, perceptive, blunt, driven, strategic...

When Tony was 9 his father told his nanny to take Tony someplace for the summer so he would be out of the way so she took him up to his grandfather's old hunting cabin by the lake. While there Tony became friends with another boy and his baby brother, their names was Dean and Sam Winchester. It was during this summer than Tony learned that vampires were real when he witness Dean's father killing on that had be preying on the people of that area.

Before Tony left for home, Dean and him exchanged address so that they could write each other, even through both of them knew it would only be a semi regular thing; for Dean because of the traveling they had to do and for Tony because his father would never approve of such a thing.

When Tony became a police officer he started to pass along to the Winchester and a few other trusted hunters information about anything strange that they might want to investigate. His home also became a place for the Winchester to crash at when need or when they needed to be patched up without questions

While Tony never hunted the creature of the night and shadows, he did became a source of information for hunters. He once suggested that someone in Hollywood was in the know about what was out there since some of the movies did come close to the truth or exactly on the nose about some creature.

Tony has always kept the darker part of his life away from his professional side… that was until folder with the name Initiative landed on Gibbs' desk.

~*~

Not sure if this is a NCIS/Xander, NCIS/Supernatural or a NCIS/Xander/Supernatural fic. Guess that's up to whoever takes it.

Could see Tony accidentally seeing what was in the folder and saying, 'That's harmless' to a photo of a demon and Gibbs asking what he knows about these.

I can see Tony wondering if he should call his old friend Dean in on this case.

Options:

Doesn't that have to be Initiative based. Could be another case in which Tony stumbles across something Supernatural and calls in his old friends while at the same time the Scoobies or New Slayer Council comes to investigate. See a lot of toe stepping while Tony tries to avoid head slaps.

Xander sucks up spirits like a kid sucks up jellybeans (He always leaves the black ones behind)

Dean sold his soul in order to bring his brother back to life. He died a year later and his soul went to Hell.

Xander walked into Hell to stop the First Evil… And when he walked out he wasn't alone.

Xander sucked up Dean's soul and carried him out of Hell and now he's stuck with Dean being a back seat driver. In order to shut Dean up and maybe find a way to free Dean, Xander hunts down Dean's brother Sam.

~*~

Xander sits down in the booth across from Sam. "Hi Sammy," he said.

"Do I know you," Sam asks cautiously.

"No, but your brother does," Xander replied before turning to the waitress. "Burger, extra onions and what type of pies do you have?"

"We have cherry, apple, lemon and chocolate," the waitress replied.

"Mmmm… cherry," Xander said as if it was the most delicious thing in the world.

"That will be right up," the waitress said before walking away.

"My brother," Sam said with a steely look. "My brother is dead."

"Yeah I know," Xander said. "He also say you better not have scratched the paint, bitch."

Sam leaned back. "Cristo."

"Won't work after all he's a spirit not a demon," Xander said. "Beside I don't think that will work on me considering where I'm from."

"Here you are sugar," The waitress said as she put Xander's order in from of him. "Let me know if you need anything. "

Thank you," Xander said before taking a big bite out of the burger. "I hate onions but Dean makes me order them. Of course I make him listen to country music."

~*~

"Here, drink," Bobby Singer order as he held out a glass of water to Xander.

Xander took the glass and drank the water. "Ah… Methodists. Nice after taste."

Sam looked at Xander then at Bobby and then back at Xander. "You can tell what religion the holy water had?"

"You can't?" Xander replied. "Catholic tend to be a bit bitter. Methodist has a sweet taste to it. Protestants has a bite."

Bobby and Sam stared at Xander in shock "And Dean can't believe you bought that."

~*~

Options:

You can have Dawn traveling with Xander in order to escape all the 'special girls'. Could have her sneeze up Dean a new body.

If you can figure out a way to get Dean a new body you could make it a Xander/Dean fic. Could make them soulmate and that why Dean was attracted to where Xander was for the battle

If you want it can be a Xander/Sam fic with Dean wondering if it's incest if the spirit of your dead brother shares the body with your lover

The Challenge

= Xander as a natural born witch from a powerful but dormant bloodline who gets his powers activated or enhanced after he becomes Luke Skywalker for the night

= Possible 2 or 3 Powers Being either Telepathy, Empathy, Telekinesis, Levitation, Hyper Speed or Premonitions with enhanced Agility 

= Personality can either be a blending of luke and xander, a result of luke influence on him before he fully fades out or a reaction to whats happened particularly if he has telepathy and heres things he shouldn't have from so called allies >  Much more Proactive, Cautious, Self Reliant, Down To Earth, Open-Minded, Practical, Calm, Maverick, Mature, Compassionate, Secure, Honest, No BS, Perceptive, Wise, Responsible, Strategic, Self Aware...

= Results in quite a lot of conflict from the others as they don't like change percieving it as a threat to their own status as well as because it forces them to look beyond the surface and confront some harsh unwelcomed truths

= Also results in some positive changes among the students outcasts such as jonathan, amy, michael, tucker, andrew... which leads them to leading fullfilling, informed and educated lives off the hellmouth

= Xander ends up working either in the military as a pilot or in law enforcement after working hard to make up for sunnydale stagnancy 

Either Pre-Series or Post Master

The whole town is thoroughly investigated by ALL relevant governement agencies which leads to a mayor death whilst resisting arrest and a full rebuilding - No more corruption, negligence, stagnancy, incompetence...etc with Key posts such as teachers, cops, doctors, therapists, managers, magic shop owner...etc being filled in by good, experienced, no BS, practical, realistic, insightful, strategic, responsible, modern and proactive: hunters, psychics, natural born witches, halfies, whitelighters...etc

The whole town is 1) thoroughly blessed and cleansed of at least 50+ years of bad energies, with the Hellmouth drained down to half strength and warded against leaking and opening, 2) cleaned out of abandoned, dangerous and hidden supernatural, magical and paranormal caches, 3) cleared of at least 60% of its vampire population

All Citizens fully cleansed of all the hellmouth corruptive taint, bonds & influence maybe through the water system which would further help in getting rid of the bad guys... 

All Kids – Forced to attend an accelerated Summer School to get up to State Education Standards for their year groups as well as good group and individual therapy {catches trouble cases before they can become threats such as Warren, Tucker, Marcy, Jonathan, Amy and her Mom, Willow...}

Willow – Sent to a good foster care family and community service for her Hacking after a stint in Juvie whilst her parents are discredited & arrested for child neglect, endangerment, abandonment...

Xander – Gets Adopted by the McNally's whilst his family is arrested for fraud, DUI, child abuse, neglect, endangerment...

Xander Rings: warded against being taken off, unwilling teleportation, physical & spiritual possessions, harmful/malicious & shoddy magicks, tracking, impersonation, mental & emotional compulsion/influence & tampering, unwilling magical & psionic bonds...

How would Giles and Buffy react to all the positive changes?, would the scooby gang still form?, would they shun the others in true council fashion?, will they actively work against the others?...

How would Xander, Jesse and Willow react to the positive changes?, would willow, xander and Jesse still be friends after everything?, will willow end up bitter about everything as she's not top academic dog anymore?...

How would Angel react to all the positive changes?, would someone be able to negate or fix his curse as well as give him a continuous reality check?...

What is Xander was one of the Y.E.D. choosen children? What if when Xander was 6 months Xander's parents took him to see Grandma? What if one the night 6 months after his birth, Xander's parents went on a date/seeing friends while Grandma baby sat? What if there was a fire in the nursey and Grandma died but Xander survived only to return to Sunnydale with his parents?

Now 22 yrs later Xander has been kidnapped by the Y.E.D. and brought to Cold Oak to fight the other children for the title of General. But the thing the Y.E.D. didn't know was that his 'spell' on Xander was wrapped by the energy of the Hellmouth. And another thing that the Y.E.D. didn't know... it's not a good thing to piss off Xander.

One night Xander Harris dress up for Halloween in some old fatigues that had previously been owned by one John Eric Winchester. That night when Ethan Rayne called upon Janus to power the spell that he has cast on the costume; John's soul and sub-conscious were sucked into Xander's body.

Many years have past since that night and John forgot all about it, chalking it up to a head injury he received while fighting some evil creature. So when John called up Y.E.D. to save Dean's life in exchange for his own life, soul, and the Colt he never thought that someone else had prior claim on his souls.

To put it simply John was a little pissed off when he woke up after his death to find himself in he body of a younger man with one eye, surrounded by a bunch of teenage girls with a voice in the back on his head cursing in a number of different languages.

Xander Winchester

Xander as a half brother or twin

1. Gets adopted by Hunter Caleb whilst age 15/16 & post Acathla or Graduation after meeting during some Sunnydale Cache raiding – Caleb helps him get a better grounding in self defence, supernatural, weapons, first aid... as well as heal from his family & friends abuse & neglect until he finds Caleb body and his Birth dad on the phone.

2. The Gang shunning him after he's forced to kill his possessed step-dad in self defence since despite being possessed he was still human & with a soul – afterwards his big brother Dean comes into town as his emergency contact whilst the gang expect Xander to crawl back to them begging for forgiveness, finds out everything that's happened, thoroughly kicks the Scooby gangs asses and then takes his brother under his wing without John knowledge whilst Sam is at Stanford{side affect could be they stopped in to see Sam & secretly de-possess his friend and put up full protections}

3. Xander bailing on the Gang after realizing at the very least how much they take advantage of him and ends up hunting alone across America until he meets the rest of his family one of three ways 1) at shotgun point in the middle of a hunt, 2) singing & playing guitar on the street, or 3) hitchhiking – side note could be Xander meeting Faith whilst on the Road and once realizing where she's going and the reason why gives a thorough heads up on sunnydale & the gang

4. Xander de-aged by willow to become more of a yes man, gets sent to his unknown to the gang, brother Sam, whilst he's at Stanford and is eventually cured by brotherly love/acceptance, Bobby or Pastor Jim

5. Teen Xander being forced to take care of his suicidal and alcohol addicted [already has issues thanks to the Harris's] half brother Sam after Dean Deal comes due whilst also struggling with keeping Ruby away from them and dealing with a sudden diagnosis of cancer

6. The hospital calling Sam at Stanford saying Xander in a bad way and Sam learning what it truly means to be the big brother whilst Xander heals = could be due to cancer, suicide attempt, returning from hell, bad hunt...etc

7. Xander as Sam twin that was stolen at birth and reunited age 16 after he'd been hunting for two years on the hellmouth & the Acathla incident – ends up going to Stanford with Sam to protect him whilst secretly keeping up with the protections, hunting on the side, working part time in a gunshop, keeping in touch with Dean & Bobby, De-possessing Brady, finding a hunter boyfriend...etc

8. Xander getting legal guardianship of half brother Adam after his mom dies and together with Xander boyfriend whose another trained hunter & Jack O'Neill clone sets out to help stop the Apocalypse whilst working out of their own home base that has enough rooms/beds for them, Dean, Sam, John, & their uncle Clay{loosers}

In each bunny the brothers each have a ring that is warded against being taken off, unwilling teleportation, physical & spiritual possessions, harmful/malicious & shoddy magicks, tracking, impersonation, mental & emotional compulsion/influence & tampering, unwilling magical & psionic bonds...

With Supernatural and Buffy crossover if Xander is a lost realtive its usually as John Winchester son or Bobby Singer nephew so this is something different.

Namely Xander as a close relative of Computer Genius/Hunter Ash who despite being a alcoholic? is very close, supportive, accepting and protective of Xander and flips his lid and rescues him when he finds out that Xander

- been fighting the supernatural since he was 13/14

- was sent to hell during the acathla incident [for no more than 30 years before being sent or brought back] OR Xander being forced to kill his willingly possessed step-dad in self defence and then being shunned for it by the Gang.

after being sent all of Xander personal possessions which includes Xander very detailed hunter journal, a devil trap poster for the ceiling, SPN database secretly created from Giles library and the detailed locations of all of Sunnydale caches-secrets.

Must haves

- Ash saving Xander when he was young from either being sold to demons or sacrified by demons worshippers

- Xander getting his own warding tattoo's after a full cleansing and medical

- Willow, Oz and Giles getting out-geniused by a kickass Ash before leaving town with Xander & a greatly enhanced bank account thanks to the town newly emptied caches

- Xander having dealt with Supernatural style demons as well as Buffy verse whilst in Sunnydale possibly without the gang knowledge.

- Xander later becoming very close to the winchester sons, as a lover, best friend, or adoptive brother

- Xander positively changing things in the supernatural universe = maybe taking out Meg before Chicago, safely destroying the devil gate keyhole, saving Ash and the Roadhouse patrons....etc

- Xander as a Psychic = Empath, Medium, Telekinetic or Clairvoyant

Alternatively you could have him as a close relative of Caleb instead afterall they are both weapons nuts.

What if Xander dressed up as youngish Charles Xavier for Halloween instead of a Soldier and he kept not only the very useful memories but the gift of Telepathy as well? Particularly if Xander thanks to the way he's grown up unconciously & constantly scans those around him for threats - hearing & finding out things he shouldn't > leading Xander to proactively taking care of various threats in sunnydale much more quietly, efficiently and effectively including the teams various attitudes as well as providing some necessary perspective for Xander with regards to his life and himself

Possibile Crossovers

1) {CHARMED} Xander finds out that he's a Natural Born Witch with Halloween just breaking through the binding, that was placed by the Elders due to his parents continuous addictions, and possibly adding another active power = gets the support/help of the Elders/whitelighters as he learns of his heritage, controls his gifts and handles sunnydale/gang > later on could move to San Francisco and form an alliance with the Charmed ones and some others in keeping San Fran safe and each other grounded in reality

1.5) Xander as just a natural Telepath, though thanks to where he was born and how he got/activated his powers still gains Elders/whitelighters support as he learns to control his gifts and handle sunnydale/the gang = later on he could also be the one to help support Leo supporting the Charmed ones and getting their heads out of their asses as needed

Added bonus if Xander and Paige become best friends, helping each other heal and supporting each other against unreasonable sisters/friends that have constant trouble accepting them as they are and not zeppo/replacement instead of friend/sister.

2) {SUPERNATURAL} Xander as one of Azazel children with his gifts coming out sooner thanks to Halloween - leads to him heading several things off

3) {SENTINAL with further possible crossovers in SGC or CSI if sentinals/guides are known} Xander as a powerful guide qualities become more telepathic in nature

4) {X-Men Evolution Or X Men The Movies} Xander as the Psychic son of the real Charles Xavier who with his own Telepathy senses that something has happened, investigates it, fixes it and then fosters/adopts Xander.

Must Not Have:- Xander telepathically powerful enough to read more than a small city

Xander has been poisoned and is dying. The only cure is a potion that is made up of certain parts from men who are like Xander; those who do what is necessary to protect other.

Willow has been able to narrow down which men they need to collect parts from and where they are at but the problem is she doesn't know what parts need to be collected from which man.

So the Slayers are sent out to collect each of the chosen men and bring them back to Cleveland so that Willow can study each man and collect what she needs from them.

Of course there will some unexpected side effects from the potion.

Xander as a experienced former full time hunter & part time Construction worker/college student out in LA after high school graduation and realizing that the other Scooby gang weren't really his friends. Ends up falling in love & secretly marrying Lindsey McDonald which unknowingly changes things in the Angel verse for the better, however Lindsey still dies several years later.

= Ends up meeting Eliot Spencer and the team a year later, after an initial freak out at seeing Eliot, ends up slowly becoming a valued part of the overprotective family, particularly by Eliot & Nate {explosive & weird crap expert, backup hitter maybe}

= Bonus points if Xander and Lindsey had two sons together before Lindsey died

= Double bonus points if Lindsey manages to up Xander confidence levels enough to believe in himself & his own talents beyond Hunting & Construction such as Music or Painting...etc
